Analysis and Evaluation of Resin Compositions of High-resin-yield Pinus elliottii in Jiangxi Province
摘要
Abstract
The chemical compositions of 186 high-resin-yield Pinus elliottii with 60 ordinary ones from Jiangxi were tested,compared and analyzed.The result showed that:the capacity of resin production was signifi-cantly positively correlated ( 0.287 1 ) with total terpenoids, and was significantly negatively correlated (-0.239 6) with total diterpenes;there was positive correlation among the whole terpenoid substances except a-pinene which was highly significantly negatively correlated withβ-pinene(-0.533 0);there was positive corre-lation among the whole Pimaric-type resin acid components,and among whole abietic-type resin acid.Futher-more,there was highly significant negative correlation ( 0.958 1) between terpenoid composition content and diterpene’ s,and there was negative correlation among almost all terpenoid components and all diterpenes.For high-resin-yield Pinus elliottii,the resin chemical compositions were special,the turpentine content was higher, and the pimaric-type resin acid content was lower than that of ordinary ones.Obviously,the slash pine in Jian-gxi with excellent resin quality was a precious germplasm resource.Therefore,varieties with higher turpentine content should be selected on the basis of high resin yield,which would not affect the quality and consequence-ly increase the contents of dipentene and myrcene.Meanwhile individuals with highβ-pinene should be select-ed.However,the pimaric-type acid content would not be increased significantly.关键词
